摘要

The Natural Resources Conservation Service (NRCS) Monitoring and Evaluation (NRCS evaluation) for three salinity control units in western Colorado (Grand Valley, Lower Gunnison, and McElmo Creek) from 1985 to 2003 was a response to the Colorado River Basin Salinity Control Act (Public Law 93–320, July 24, 1974) and its amendments. The NRCS evaluated the effects on seasonal irrigation efficiency and deep percolation of irrigation water of various on-farm irrigation system improvements in the three salinity control units, and reported the results in a series of internal NRCS annual reports. Because of the large amount of effort and expense that went into the NRCS evaluation and the importance of the data to help quantify the changes to deep percolation, the NRCS has determined that having the evaluation results made public through a characterization and analysis of the results by the U.S. Geological Survey (USGS) could be of use to a wider audience of water managers and the general public. In 2011, the USGS, in cooperation with the Bureau of Reclamation and the Colorado River Basin Salinity Control Forum, began a study to evaluate the NRCS evaluation data to (1) document the methods of the evaluation, and (2) analyze and summarize the data collected during the evaluation.
